Air tool help

[Cuz]

I have a compressor (6 gallon 1.5hp). I just bought a couple air tools. A cut off tool/grinder and an air ratchet. When I first turn them on they RUN! for about 10 seconds and then lose their speed/power, until I let me compressor fill back up.
So I'm thinking my compressor is not either big enough in capacity or the motor isn't strong enough to keep up. Or maybe both.
Do I need a new/bigger compressor to work these tools effectively? If so, any advice on tank size and HP motor I'd need to run basic home shop air tools?
Thanks brain trust!

You need a bigger compressor. I'm running a 60 gallon with 7.0 HP.

Much bigger tank, probably 50 gallon minimum to effectively run air tools.

The tank have a regulator that can keep the tank at a certain pressure so it doesnt get depleted to the point the tools are working at a lower pressure when the compressor kicks in?
bigger is always better..more capacity on tap ..longer it will run.

subscribed to see if any of the big shop guys have tips on using smaller capacity units

This is what it takes for continual use of air tools. dropem knows

I run a 30 gallon with 2hp motor......the larger ones are nice and if I were using it for work I would get a 60+gallon setup, but for around the house the smaller unit does just about everything I need it to.....if I'm working it hard though I will still have to wait a minute or so to let it catch up on occasion.

Sounds like you need a bigger tank.

Looks like BigTex.308 still has his for sale.

If you want something smaller I have a 30 gallon compressor at the house. It's not for sale but you can borrow it to see if it will do what you need.

You need more tank. Also make sure you set your regulator for the tools you are using to the proper spec.

Cut off tools and DA sanders are the biggest air hogs, from my experience.

You could probably run the air ratchet with what you have, but for any extended use, you're going to need more capacity, for the cut off tool.

I had a 60 gallon, that would pretty much keep up with my DA sander, but you'd still need to give it some catch-up time every now and then.

It's already been said, but your compressor sounds like the popular pancake style compressors. They are great for fastening tools but using just about any other air tool beyond nail guns is going to require a much lager tank and pump.

Not enough volume. Need bigger tank which needs bigger compressor to handle your volume needs. I have a 50 gallon and it barely keeps up.

[Big Lee]

Bigger tank and compressor. Pay good money on one and it will last forever.

The one I have now is a lot like this. Not exactly but you get the idea...

You guys think this one would do the job? Not heavy, all day use. Just cutting here and there and basic house shop stuff.
